set correct nesting when adding container

[arve0]

To reproduce:

let md = require('markdown-it')();
let container = require('markdown-it-container');

md.use(container, 'column');

let src = `
::: column
Lorem ipsum
:::
`;

console.log(md.render(src));

gives tokens:

[
  Token {type: "container_column_open", tag: "div", attrs: null, map: Array(2), nesting: 1, …},
  Token {type: "paragraph_open", tag: "p", attrs: null, map: Array(2), nesting: 1, …}
  ...
]

Note that div and p both have nesting === 1, which is incorrect, as p is inside div.

This results in https://github.com/arve0/markdown-it-attrs/issues/72, attributes on the wrong opening tag.

It is correct. Nesting does not represent a level of nesting, it represent a change of level of nesting.

See here for more details.

I believe what you are looking for is level property which is hidden behind … in your dump.
